Application filed March 13, 1928. Serial No. 261,229.

This invention relates to wrist watch straps and particularly to that type which is madefin two sections, each attachable toone of the ears of the watch and removable attachable to each other, and in which bends are formed for enclosing the watch ears.

My invention contemplates, among other things, the provision of simple and effective means for enclosing the watch ears, and for holding the doubled over ends of the strap sections in place while allowing the quick and easy detachment of the parts from the watch when desired.

The various objects of my invention will be clear from the description which follows, and

from the drawings, in which,

Fig. 1 is a perspective view of a wrist watch strap embodying my invention as it appears when passed through the ears of a watch.

Fig. 2 is a similar View of a modified form of means for holding one end of one of the strap sections in place. I r

Fig. 3 is a similar view of the same showing a modification wherein certain stitchingis omitted. v

Fig. 4 is a similar View of a buckle end of one of the strap sections showing another modification applied particularly to a double buckle.v

Fig. 5 is a similar view of the same another modification.

Fig. 6 is a similar view of the same showing still. another modification.

Fig. 7 is a similar view of one end of the buckle section showing particularly how the metal loop is secured to the strap section, and

.Fig. 8 is a similar view of part'of the per-. forted section showing the means for securing the metal loop thereto.

In the practical embodiment of my invention which I have illustrated, the strap consists of two sectionslO and 11,.the former section being designated as the perforated section herein and the latter section being designated hereinafterv as the buckle section. One or both of said sections, as usual may be made with a finished face and an unfinished face, it being intended that the unfinished face be hidden either bysuitable bending or overlapping of the sections or on: the inside thereof and against the wrist of the wearer. Thewrist watch'is indicated by the numeral 12 andas usual is provided'with cars 13 and 14; which are engaged by the respective strap sections, and removably held therein by bends showing in the sect-ions adjusted to enclose theyizateh stitching and that the cars by means of metal loops suitably secured to the sections. v

One end 15 of the perforated section 10 is provided with perforations as 16, and is adapted to be passed through the frame of the buckle 18 for engagement by the tongue 17 thereof. However if a tongueless buckle,

of any well known type is used, the perit forations 16 may be omitted, the end 15 being held. in place by the swinging member of the buckle in the usual manner. The other end of the perforated section is bent back .onitself for a short distance to 19, in which the loop 20 of metal or other suitable material is held, as illustrated in,

Fig. 7 In order to decrease the thickness or in other words to flatten the bent end 21 of the perforated section, if desired, I may provide the stitching 22 in close proximity to the bend, in addition to the stitching 23 on the other side of the loop 20, though it will. be understood that through out staples may be substituted for any of the stitching 22 maybe omitted as shown in Fig. 1. It will be noted that the end flap 24L forming-the bend 21, is bent on to the unfinished face of the per forated section 10,;whereby the loop 20 is preof the wearer.

form an opening I I prefer to make the depth of the loop 20 such, that there is just room enoughtherein forthe flap 241- and for the'body portion of the perforated section 10- to pass there through, so that there is left little or no room for displacement. To secure .sa-idsection in plac'e'about the ear 14:, the end 15 is passed I through the car from the inner or wrist side to the outer side and then through the loop 20,

thereby forming the bend 21 hugging the car 14 when the section 10 is pulled through the loop a sufiicient distance to bring the loopy close to the ear.

The bucklesection 11 is also preferably providedwith a metal loop 27 suitably held on to the inner or unfinished face of the inner length 28 of said section, as by means of a short piece of material 29, or staples or other suitable means. Where the strip 29 is used, it

is held to the unfinished face of the length 28 as by means of the lines of stitching 30 and 31 arranged about midway of the ends of the section 11. I j

As illustrated in Figs. '1, 2 and 3, the buckle element 18takes the form of what is known as a single buckle, wherein the tongue 17'is hinged to one of the outer cross members 32 of the buckle. Where a single buckle is used the end 15 of the perforated section 10, being otherwise loose should be removably securable in place, and this is preferably accomplished by the loop 33, which is also preferably made of metal. The buckle-holding flap 34 at the end of the length 28 is slotted as at 35 to allow the tongue 17 to project therethrough and the flap is seamed in place about the cross member 32 as by means of the stitching 36 whereby the buckle is securely held in position. It will be noted that in the length 28,

I the finished surface 37 thereof is arranged adjacent to the wrist while the inner or un finished face 38 is hidden from view by the integral length 39 of the buckle section.

It will also be seen that the buckle is secured in reversed position on the length 28, or in other words, that the tongue member 17 is on the same side of the buckle frame as is the unfinished or inner surface 33, and is arranged to swing away from the wrist. The length 39 of the buckle section 11 is passed through the car 13 of the watch from the inside to the outside thereof and through the loop 27 thereby forming the bend 4O constricted by said loop in which bend the ear is securely held against displacen'ient. I

Means are prov1ded for holding the otherwise free end of the length 39 removably in position. 'As illustrated, said meanstakes the form of a hook, adapted to pass through a suitable slit or perforation near the end of the length 39. Referring now to Fig. 1, I have there shown a hook member 41 preferably formed of sheet metal and having a hooked end 42 adapted to pass through the slit or per-- fora-tion 43 in the end of the length 39. In the form illustrated, one end of'the hook member is'bent about the central part of the enclosed portion of the loop 33, and the body of the member passes through a slot in the flap 34. Stitching as 45 may serve to secure the end of the flap in position, and at the same time aid in preventing detachment of the loop 33 though it will be'understood that said stitching may be entirely omitted if desired as indicated in Fig. 3. The slot 35 alone in that case, serves to prevent loss or movement of the loop 33 and of the hook 41 secured thereto. In the construction shown in Figs. 1 and 4, the hook part of the hook 41 is hidden when the strap is assembled, and only a flat band is visible. 1

As illustrated in Figs. 2 and 3, the hook end 42 may be bentoutwardly insteadiof inwardly so that only the end parts of the hook are visible when the strap is worn.

Referring now to Figs. 4. 5 andG l have there shown a double buckle 46 secured in lace at its intermediate cross bar 47 by 7 .i

Since one end of the frame of the double serted between the flap 34 and the inner face 38 of the length 23, and integral with the hook 41, or of a separate piece as desired, stitching 45 being used or omitted as may be desired. in Fig. 5 I have shown the hook 41 held in place by a suitable fiange or eyelet 50 passing through the flap 34 and the length 28, or through either alone, if desired. The eyelet 50 may be madeintegrally with the remainder of the hook member or it may be made in a separate piece, as is well known,

I and neednottherefore be described in detail. In Fig. 6 I have shown the hook member 41 provided with an enlarged base 51 from which the prongs 52 project. Said base may be arranged between the flap 34 and the inner face 38, and forced through the said flap. or through suitable slits therein, and then bent over on to the outer face of said flap thereby securing the hook 41 in position. It will be seen that I have provided a simple, inexpensive, though eihcient wrist watch strap easily removable and attachable to the watch ear and simple and effective means easily secured in position for removably securing the otherwise free doubled ever end of a section in place with a minimum of labor and materials.

While I have shown and described certain possible embodiments of my invention in detail, I do not intend to limit myself thereto, since various changes therein will be apparent to those skilled in the art, but I intend to claim my invention as broadly as maybe permitted by the scope of the prior art and the terms of the appended claims.
